Hi guys,

I need help with another engine question. I purchased a OS FS-91 Surpass (not Surpass II, etc., it's an early one). It needed bearings but that seemed about all. I fired the engine up on...

RE: OS engines users Club

OK, thanks Bruce.

I think I'll get another body - this one may be shot. I'll give it one last look before I order the part.

Thanks,
